Hi I have an electrical problem with my 1996 4.6 HSE P38 Automatic. The suspension lowers and a caution light and a do not exceed 55KPH message appears on the instrument panel. The air compressor is running and there is no sign of any air leaks, I suspect a power supply to the EAS ECU issue. Having brought an online workshop manual without wiring diagrams I'm struggling to make sense of the system. Does anybody know where to find the suspension electrical diagram online or what are the power supply and earth pin numbers on the ECU plug?
